Abstract (en)

Techniques are directed toward secure scrambling. An example method includes a first device encrypting a payload to be included in a physical layer protocol data unit (PPDU) frame. The determining a PPDU frame type based at least in part on an association with a second device. The first device can select a key based at least in part on the association with second device. The first evice can encrypt a payload to be included in a physical layer protocol data unit (PPDU) frame. The first device can determine a PPDU frame type based at least in part on an association with a second communication device. The first device can obfuscate the field of the MAC header. The first device can scramble the encrypted payload using a service field value. The first device can transmit the PPDU frame to the second device.
